626-2Z/C3GWP Bearing Product Overview & Core Advantages
The 626-2Z/C3GWP is a metric single row deep groove ball bearing engineered for exceptional performance in demanding applications. This precision bearing features integral shielded protection and is pre-lubricated with high-quality grease, offering reliable operation and long service life. Its design is optimized to handle significant radial loads while also accommodating moderate axial loads in both directions. With its compact dimensions (6mm bore, 19mm OD, 6mm width) and C3 radial internal clearance, it is ideally suited for applications requiring robust performance across a wide temperature range and under varying operational conditions.
626-2Z/C3GWP Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Performance Implication |
|---|---|---|
| -2Z | Non-contact steel shields on both sides | Provides effective protection against contamination while minimizing friction, contributing to the high limiting speed of 32,000 rpm. |
| /C3 | Greater than normal radial internal clearance | Accommodates thermal expansion in applications with high operating temperatures or heavy loads, preventing premature failure. |
| GWP | Pre-lubricated with Grease | Ensures immediate, maintenance-free operation upon installation, ideal for sealed-for-life applications. |
626-2Z/C3GWP Bearing Structural Features & Performance Benefits
Constructed entirely from chrome steel for the rings, balls, and cage, the 626-2Z/C3GWP delivers high durability and consistent performance. The single row deep groove raceway geometry is fundamental to its high radial load capacity (447 lbf dynamic, 161 lbf static) and its ability to handle combined loads. The shielded design (2Z) effectively retains the factory-applied grease and excludes larger contaminants, significantly extending the bearing's service life without the need for re-lubrication. The specified C3 clearance provides operational stability in environments prone to thermal expansion, making this a versatile and high-reliability component for a wide array of industrial machinery.
626-2Z/C3GWP Bearing Typical Application Areas
This bearing's compact size, high-speed capability, and robust construction make it a preferred choice in numerous precision applications, including:
- Small electric motors and high-speed spindles
- Precision gearboxes and transmission systems
- Industrial fans and blowers
- Office automation equipment (printers, scanners)
- Medical and dental handpieces
- Robotic joints and small automation drives
